| 摘 要： | 目的研究珠子参Panax japonicus种质资源的遗传多样性。方法采用ISSR分子标记技术,通过聚类分析和主坐标分析,研究3个主要产地珠子参的19个样本的遗传多样性和亲缘关系。结果 13条ISSR引物扩增出181条带,其中有166条呈现多态性,占91.71%,遗传相似系数变化范围0.60~0.83。聚类分析和主坐标分析结果一致,将源于同一地区的珠子参样本聚在一起,呈现出一定的地域性分布规律。结论珠子参样本之间的遗传多样性水平较高,种质间的亲缘关系和地理位置有一定关系。

| Abstract: | Objective To analyze the genetic diversity of Panax japonicus var. major by inter simple sequence repeat (ISSR) molecular makers. Methods Genetic diversity of 19 samples from main production areas was investigated by ISSR and analyzed by principal coordinate analysis and UPGMA cluster analysis. Results A total of 181 bands were generated by 13 ISSR primers, among which 166 bands (91.71%) were polymorphic bands (PPB). The coefficient of genetic similarity ranged from 0.60 to 0.83. The results of UPGMA cluster analysis and principal coordinate analysis showed that the genetic diversity of P. japonicus var. major from the same region presented a geographical distribution regularity. Conclusion The results of ISSR analysis reveals that P. japonicus var. major has a high genetic diversity level and the genetic relationship closely contacts with the geographical location. |
